Codorus Forge and Furnace Historic District, also known as Hellem (Hellam) Forge, is a historic iron forge and national historic district located at Hellam Township in York County, Pennsylvania.

The ironmaster's house is a 2 1/2-story, stuccoed stone building, nine bays wide and one room deep.

[1] The Codorus Furnace is currently owned and maintained by the Conservation Society of York County.

The organization is conducting a campaign to restore and reinforce the structure, as well as the nearby charcoal house foundation.

In 2023 and 2024, an Eagle Scout project by a Scout from Dover, PA was completed which added steps and safety railings that added accessibility to the trails behind the furnace, which lead to the charcoal house and into the Susquehanna Riverlands State Park.
